Correct Prerequisite step in readme

[zevlramos]

Hi! This has been a super useful adapter for the interim, so thanks!
I just noticed one SUPER tiny detail that could be corrected.

In the prerequisites section where you say:

CSharpLspAdapter/README.md

Lines 39 to 44 in 97251fe

	### Prerequisites
	> **Important:** If you have the official `csharp-ls` plugin installed from the Claude Code store, you must completely uninstall it first:
	> ```
	> /plugin uninstall csharp-ls
	> ```

this should be updated as the below (it should be updated from csharp-ls -> csharp-lsp) as csharp-ls is the lang server itself from nuget, while the claude code plugin is csharp-lsp :)

### Prerequisites

> **Important:** If you have the official `csharp-lsp` plugin installed from the Claude Code store, you must completely uninstall it first:
> ```
> /plugin uninstall csharp-lsp
> ```

Thanks again for this!
